Diligence is the mother of success.
勤奋是成功之母。
Truth is the daughter of time.
时间见真理。
Take care of the pence, and the pounds will take care of themselves.
积少自然成多。
No man is wise at all times.
智者千虑，必有一失。
Never put off till tomorrow what you can do today.
今天能做的事绝不要拖到明天。
Live and learn.
活到老，学到老。
Kill two birds with one stone.
一石双鸟。
It never rains but it pours.
祸不单行。
